8 N₂O + 4 CS₂ → S₈ + 4 CO₂ + 8 N₂
The "Barking Dog" is an exothermic chemical reaction ignited by a mixture of carbon disulfide and nitrous oxide. This combustion process, occurring in a cylindrical tube, results in a bright flash and a distinctive "woof" sound, reminiscent of a barking dog. Simply put, it involves the reaction of carbon disulfide (CS₂), a fuel, with nitrous oxide (N₂O), an oxidizing agent, leading to the production of heat and elemental sulfur. The flame front in this reaction is a zone of highly luminous and hot gas, formed by the decomposition of the reactants.
